Description

The Mallee Tract of the River Murray contains free-flowing reaches and weir pools that allow a direct comparison of the effects of weirs on biofilm characteristics. In this study, River Red Gum substrates were deployed at various depths in the water column for 6-9 weeks and the biofilms that established were sampled so as to: 1. Compare biofilm composition in weir pools and free-flowing reaches of the Mallee Tract of the River Murray. 2. Examine changes in biofilm composition with water depth in the Mallee Tract of the River Murray.
